Section 7 ♦ Troubleshooting
WARNING: These instructions are for use by qualified personnel only. To reduce
the risk of electric shock, do not perform this installation or any servicing unless you
are qualified to do so. Refer all servicing to qualified service personnel.
NOTE: When power is applied to the unit, the display shows the startup screen for about 45
seconds.
If the TVM is not functioning properly, first verify that:
• The TVM is connected to a power source (90–264 VAC, 50/60 Hz nominal).
• All cables are correctly connected (see Section 2, "Installation").
Initial difficulties with operation or display can be due to improper setup. Review the
SETUP MENU (see Section 3, "Operation") to ensure that the proper adjustments have
been made for the signal requirements.
Cold Starting the TVM
NOTE: A cold start resets all front panel and Setup menu selections to the factory-default
settings. All user settings are lost. See Section 3, "Operation," for the factory-default settings.
If a problem persists after the cables are correctly connected and the unit is set up,
perform a Cold Start. Only one procedure needs to be performed to cold start the unit.
The first type of cold start procedure is a front panel Cold Start, as described below.
The second type of cold start procedure is a Warm Start that is described on page 211.
The third type of cold start is a Cold Start after a VFlash update that is described on
page 212. The Ethernet default settings for the TVM are:
• IP: 192.0.0.100
• Subnet Mask: 255.255.255.192
• Gateway: 0.0.0.0
Cold Start
The Front Panel Cold Start procedure is a cold starting procedure that does not require
the power to be disconnected from the unit. To perform a Front Panel Cold Start:
1. Push and hold the SETUP button, UP/DOWN knob, and RIGHT/LEFT knob. For a
minimum of five seconds. The Cold Start message appears on the screen.
2. Once the message appears, the cold start is complete.
Warm Start
The Warm Start procedure is similar to a cold start. This reset will perform a cold start
on the unit, but will not erase the Presets from memory. To perform a Warm Start:
1. Push and hold the SETUP button and CURVED ARROW knob for a minimum of
five seconds until the Warm Start message appears on the display.
